V2 must be printed in the given orientation (flat side of the bolt-locked legs down). I recommend using mouse ears around the bolt-lock legs and key slot.

V2 can be attached to an octagon plate by bolt-locking the top bars to a mid-hole snap of your choice and push-fitting the bottom bars to a regular, mid-hole snap. It can be attached to a square plate with a mid-holes square-plate snap.

V1 can be printed on the face with the battery hole or either of the octagon faces down. I recommend mouse ears on the corners.

V1 can be attached to a tile with one to three Snap-to-Snaps.
